I had an issue come up in-game with this creature.
One of my players cast globe of invulnerability in this fight. The spell reads:
You create an immobile globe around you that attempts to dispel
any spell from outside the globe whose area or targets enter into
the globe, as if the globe were a dispel magic spell 1 level lower
than its actual spell level. Even if the dispel attempt succeeds, it
prevents only the portion of the spell that would have entered the
globe (so if the spell also had targets outside the globe or part of
its area were beyond the globe, those targets or area would still
be affected normally). You must form the sphere in an unbroken
open space so its edges don’t pass through any creatures or
objects or the spell is lost (though creatures can enter the area
afterward normally).
My question is are the poltergeist's Telekinetic Object attack (and Telekinetic Storm) considered spells? I ruled no at the table, but I am not positive I made the right call as they possess the Evocation and Occult traits, as well as being similar to the Cantrip Telekinetic Projectile. Furthermore, the occult trait reads:
This spell or magic item comes from an occult spellcaster
or from the occult magical tradition.
I would thus assume it was a spell since it has this trait, but what is the spell level then?
Also, from a logical perspective, the "spell" in this case would be to hurl the object. Once the object was in motion, there is no magic affecting it, so there should be nothing for the Globe of Invulnerability to dispel.
